MACHINE FOR IMPARTING. ROTARY MOTION.

SPECIFICATION forming part ef Letters-Patent No. 762,126, dated June 7,1904.

Application filed June 8, 1903. Serial No. 160,554. (No model.)

To @ZZ whom, it may concern:

Be it known that I, SAMUEL C. BOND, a citizen of the United States,`residing at Wilmington, in the county of Newcastle, State of Delaware,have invented a new and useful Improvement in Machines for ImpartingRotary Motion, of which the following is a speciication.

My invention relates to a machine that will impart rotary motion todrills, reamers, taps, &c., in which simplicity, durability,adaptability, and minimum cost of construction have been some of theprincipal objects sought.

1t further consistsof novel means of reversing the motion as required intapping, &c.

It further consists of other novel features of construction, all as willbe hereinafter fully2 casing, to which is secured the cylinder2, saidcylinder having the annular recess 3, connecting with theports 4, `5,and 6, and the annular recess 7, connecting with the ports 8, 9, and 10.Y

1l designates the upper cylinder-head, in which operates thefeed-extension sleeve 12, the feed-screw 13 having the point 14 on oneend thereof and the thread-stop 15 on substantially the other endvthereof, said feed-screw 13 being carried by said extension 12 andcooperating therewith.

16 designates the feed-grip, which is suitably secured to the feed-screw13.'

17 designates the stationary gear, which is suitably secured to theupper cylinder-head 11.

18 designates the piston, having on the circumference thereof thedepressions or iats 19, on which roll the abutments 20, said abutmentsbeing retained in the peripheral recesses 21 in the cylinder 2.

21:l designates a check-valve connecting an annular recess 3 or 7 with arecess 21.

22 designates the bearings in the piston 18, in which rotate thedriving-pinions 23, 24, 25, and 26, said pinions engaging and drivingthe differential gear 27, which is suitably secured to the spindle 28,said spindle having therein the socket 29.

designates the thrust-bearing, shown as a pair of ball-races carryingthe usual balls.

31 designates the handle-retaining nuts, which secure the handles 32 and33 to the casing 1, said handle 33 having the ports 34 and 35 thereinleading from the valve-chamber 36 to the annular recesses 3 and 7 andcontrolled bythe valve 37, said valve being operated by the hand-lever38.

39 designates the exhaust-port, which is l thrown into communicationwith the ports 34 or 35 by the valve 37 and lever 38, as desired. 4()designates the lower cylinder-head, having-the spindle-bearing 41therein, said head being suitably secured to the cylinder 2.

42 designates the hose attachment, and-43 the motive-Huid inlet.

44 designates the tang-grip for securing the tools from rotating. 45 and46 designate the springs'for holding the hand-lever 38, so that themotor is normally inoperative.

The operation is as follows: In tapping or'v operations of a similarnature a tap is placed in the socket 29 and the motive-Huid conveyersecured to the hose attachment 42. The action of the hand on the lever38 in forcing the machine forward to cause the tap to start places thevalve 37 in the position shown in the drawings by dotted lines, therebyforming a passage for the motive iiuid to the port 34, said motive iiuidpassing through the port 34 into the annular recess 3, through theannular recess 3 to the ports 4, 5, and 6, through said ports into thevcylinder 2, when the depressions 19 of the piston 18 are incommunication with said ports, said motive iiuid reacting on theabutments 2O and revolving the piston 18, the power at any time beingdue to said reaction and in proportion to the amount of projected areaof the abutments 20 in the cylinder 2. It is understood that theabutments 2O are in the construction shown held against the piston 18 byfiuidpressure admitted through the check-valves 21a. When thedepressions 19 have passed out of communication with the ports 4, and 6,the motive Huid contained therein is carried idly until it reaches theports 8, 9, and 10, passing' therethrough to the exhaust-port 3 9 by wayof the annular recess 7 the port 35, and valve 37. In reversing' themovement of the piston the action of the hand on the lever 38 in tryingto withdraw the tool forces the hand-lever 38 and the valve securedthereto to the position shown in full lines in the drawings, the port 84being in communication with the exhaust-port 39 and the port incommunication with the inlet 43, thereby causing the motive fluid toflow in the opposite direction from that described above.

' The piston 18, having the bearings 22 therein, in which the shaftscarrying' the pinions 23, 24, 25, and 26 rotate, said pinions 23 and 24meshing with and revolving around stationary gear or rack 17, inconjunction with the pinions 25 and 26, imparts a greatly-reduced speedto the gear 27 and spindle 28, this being due to the differentialarrangement of the teeth in gear 27.

The feed-screw is operated as follows: The power is applied to thefeed-grip 16 and the feed-screw 13 removed until the thread-stop 15engages with the feed extension 12, when a continued movement of thefeed-grip 16 causes the said extension to rotate, thereby obtaining anincreased length of feed, as will readily be seen by referring to thedrawings.

I desire to call particular attention to the fact that all the partsrevolve around a common center and that in any position of said parts aperfect pressure balance is maintained; also,that the abutments rollinstead of slid ing, as in machines constructed heretofore.

It is evident that means other than that shown may be used to maintainabutments 21 against thc depressions 19 in the piston 18. Thus eitherthe piston or the abutments may be magnetic, the adjacent parts being ofdiamagnetic material. By making' the number of depressions 19 greater oreven less than that of the recesses 21 a more even movement of thepiston 18 is attained.

It will be evidentthat various changes may be made by those skilled inthe art which will come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isw
